Abstract The human brain relies on a complex network of connections to function, with white matter acting as the primary communication highway between different brain regions1,2. Disruptions in these critical communication pathways are linked to several neurological, psychiatric and developmental disorders3,4.

Abstract Magnetic resonance spectroscopy (MRS) is one of the few non-invasive imaging modalities capable of making neurochemical and metabolic measurements in vivo. Traditionally, the clinical utility of MRS has been narrow. The most common use has been the "single-voxel spectroscopy" variant to discern the presence of a lactate peak in the spectra in one location in the brain, typically to evaluate for ischemia in neonates.
